TECHNICAL FIELD

The present disclosure relates to the field of storage of materials with pallets. More specifically, the present disclosure relates to the adjustment of pallets for delivery on rooftops.

BACKGROUND

Pallets are well known in the art, as a cost effective means of stacking materials for storage, and moving the stacked materials from one place to another by transporting the pallets with a dedicated pallet transporter, for example fork lifts or boom trucks.

In the context of rooftop construction, pallets are used to store and transport shingles. The shingles are packaged in bags, which are further stacked on pallets. The pallets may be initially stored at a warehouse, and then transported to the location where rooftop construction is occurring. In the case where the rooftop has an inverted V shape, a pallet cannot be delivered to rest on the rooftop, since a pallet can only be resting on a substantially planar surface. Thus, the content of the pallet (e.g. the bags containing the shingles) is manually offloaded by construction workers to the rooftop.

Therefore, there is a need for a system allowing delivery of goods stored on pallets on inverted V-shaped rooftops.

SUMMARY

In accordance with a first aspect, the present disclosure relates to a system for dropping off a pallet on an inverted V-shaped rooftop. The system comprises two adjustment assemblies for resting the pallet on the inverted V-shaped rooftop. Each adjustment assembly is adapted to rest on one of two sides of the inverted V-shaped rooftop. The system further comprises means for securing the two adjustment assemblies to the pallet.

In accordance with a second aspect, the present disclosure relates to an improved pallet for dropping off on an inverted V-shaped rooftop. The improved pallet comprises a regular pallet for supporting a load. The improved pallet further comprises at least two adjustment assemblies for resting the regular pallet on the inverted V-shaped rooftop. Each of the at least two adjustment assemblies is adapted to rest on one of two sides of the inverted V-shaped rooftop. The improved pallet also comprises means for securing the at least two adjustment assemblies to the regular pallet.

In a particular aspect, each adjustment assembly comprises a longitudinal supporting member for resting on one of the two sides of the inverted V-shaped rooftop.

In another particular aspect, each longitudinal supporting member defines a specific angle with a vertical axis, the specific angle being substantially equal to an angle defined by one of the two sides of the inverted V-shaped rooftop with the vertical axis.

In still another particular aspect, two adjustment assemblies, respectively resting on one of the two sides of the inverted V-shaped rooftop, define an adjustment frame. The adjustment frame comprises the two longitudinal supporting members, a horizontal upper member, and two vertical members. An upper edge of each of the two longitudinal supporting members is attached to a central section of the horizontal upper member. An upper edge of each of the two vertical members is attached to an edge of the horizontal upper member. A lower edge of each of the two vertical members is attached to a lower edge of one of the two longitudinal supporting members.

In yet another aspect, the improved pallet comprises two or more adjustment frames.

In another aspect, the adjustment assemblies are permanently secured to the regular pallet.

In still another aspect, the adjustment assemblies are retractable from a first to a second configuration. The adjustment assemblies are positioned in the first configuration when the regular pallet is resting on the inverted V-shaped rooftop. The adjustment assemblies are positioned in the second configuration when the regular pallet is resting on a substantially planar surface.

In yet another aspect, the adjustment assemblies are initially not secured to the regular pallet; and the adjustment assemblies are secured to the regular pallet before resting the regular pallet on the inverted V-shaped rooftop.

DETAILED DESCRIPTION

The foregoing and other features will become more apparent upon reading of the following non-restrictive description of illustrative embodiments thereof, given by way of example only with reference to the accompanying drawings. Like numerals represent like features on the various drawings.

Various aspects of the present disclosure generally address one or more of the problems related to the use of a pallet on an inverted V-shaped rooftop.

Terminology

The following terminology is used throughout the present disclosure:

Pallet: a flat transport structure that supports goods in a stable fashion while being lifted by a forklift, pallet jack, front loader or other jacking device. The pallet usually comprises an upper flat platform for receiving the goods and a lower flat platform for lying on the ground. The two platforms are secured to one another by an assembly allowing lifting of the pallet. A pallet is generally made of wood, but is not limited to such a material.

Usage of Pallets in Rooftop Construction

Referring to FIGS. 1A, 1B and 1C concurrently, the structure of a pallet is described and the issue of using a pallet in the context of rooftop construction is illustrated. FIG. 1A represents a side view of a pallet 10, FIG. 1B represents a bottom view of the pallet 10, and FIG. 1C represents a side view of the pallet 10 with its load 20 and a partial cross-section view of a rooftop 30. The pallet 10 is for illustrations purposes only. Other designs and structures of pallets may be found, based on a specific use of the pallet and a specific industry where the pallet is used. However, a common characteristic to all types of pallets is that they are designed to be laid on a substantially flat surface (e.g. on a substantially flat ground of a warehouse, on a substantially flat ground outdoor, on a substantially flat surface of a building in construction, etc).

The pallet 10 comprises an upper flat platform made of longitudinal upper members 14 for supporting the load 20 deposited on the pallet 10. The pallet 10 also comprises a lower flat platform made of longitudinal lower members 12 for laying the pallet 10 on a substantially flat surface. The upper platform (consisting of the longitudinal upper members 14) and the lower platform (consisting of the longitudinal lower members 12) are secured to one another by longitudinal intermediate members 16. The longitudinal intermediate members 16 are perpendicular to the longitudinal lower members 12 and upper members 14. A top view of the pallet 10 is similar to the bottom view of the pallet 10 represented in FIG. 1B. Although the pallet 10 is represented with the same number of longitudinal upper members 14 and longitudinal lower members 12, this number may vary. For example, in an alternative configuration, the number of longitudinal lower members 12 may be lower than the number of longitudinal upper members 14.

The load 20 of the pallet 10 is positioned on the longitudinal upper members 14. For example, the load 20 may consist of bags 22 stacked on the pallet 10, each bag containing materials to be stored on the pallet 10. The bags 22 may be arranged in various configurations on the pallet 10. For example, as illustrated in FIG. 1C, the bags 22 may be arranged in a certain number of rows, each row containing a vertical stack of three bags 22. The load 20 may be secured with appropriate means (not represented in FIG. 1C) to the pallet 10, to maintain the load 20 in position during transport of the pallet 10.

In the context of rooftop construction, the materials stored on the pallet 10 may consist of shingles, and the shingles may be packaged in a set of bags 22 stacked on the pallet 10. The shingles being used while working on the rooftop, they need to be lifted on the rooftop and stored on the rooftop. A practical way of storing the shingles on the rooftop may consist in lifting the pallet 10 on the rooftop and resting the pallet on the rooftop. The materials stored on the pallet 10 may also consist of terracotta tiles, slate tiles, rolls of membrane, etc.

However, as illustrated in FIG. 1C, most rooftops 30 have an inverted V-shaped configuration. Specifically, the inverted V-shaped rooftop 30 has two sides 32 and 34 which define the inverted V. Thus, an upper surface 36 of the rooftop 30 is not flat, and therefore it is not possible to rest the pallet 10 on the rooftop 30 in a secure manner. For instance, resting the pallet 10 on one of the sides 32 and 34 cannot be considered (in the general case) to be a secure manner of resting the pallet 10 on the rooftop 30. For example, the slope of the rooftop 30 may be too stiff for the pallet 10 to remain in position when rested on one of the two sides 32 and 34 (even if securing means are used to secure the pallet 10 to the rooftop 30). Additionally, the weight of the load 20 may be an additional factor preventing the pallet 10 to remain in position.

The usual way to proceed in such circumstances is to lift the pallet 10 from the ground to the rooftop 30 (with an appropriate lifting machine), and to have construction workers manually off load the material on the pallet 10 at different locations 50 and 52 on the rooftop 30. There is sometimes a need to distribute the off loaded load 20 at different locations 50 and 52, because the off loaded load 20 is two heavy and/or too large to be secured to the rooftop 30 at a single location. For example, if the load 20 consists of bags 22 containing shingles, one or several bags may be dropped to the rooftop 30 at each of the different locations 50 and 52. However, if there are many bags, the bags are usually scattered during off loading of the pallet 10 at the different locations. Furthermore, it is not possible to deliver a pallet of materials to be dropped off on the roof, thus requiring that materials stocked on pallets to be delivered to roof tops be delivered only during working hours, and when construction workers are available to off load the materials on the pallet. FIG. 1D illustrates a prior art way to store materials on the rooftop 30, where a support 38 (e.g. made of wood) is secured to one side 34 of the rooftop 30, and bags 22 containing shingles are stacked on the support 38. FIG. 1E illustrates another prior art way to store materials on the rooftop 30, where bags 22 containing shingles are stacked on the top of the rooftop 30. There is therefore a need for a system allowing a pallet to be securely rested on an inverted V-shaped rooftop.

System for Adjusting a Pallet to an Inverted V-Shaped Rooftop

The present disclosure relates to a system for adjusting a pallet to an inverted V-shaped rooftop. The system comprises two adjustment assemblies for resting the pallet on the inverted V-shaped rooftop. Each adjustment assembly is adapted to rest on one of two sides of the inverted V-shaped rooftop. The system further comprises means for securing the two adjustment assemblies to the pallet.

Referring to FIG. 2, a side view of the system for adjusting a pallet 10 to an inverted V-shaped rooftop 30 is represented. The system comprises the two adjustment assemblies 100 and 200. The adjustment assembly 100 is adapted to rest on a first side 32 of the rooftop 30. The adjustment assembly 200 is adapted to rest on a second side 34 of the rooftop 30. The adjustment assemblies 100 and 200 represented in FIG. 2 are for illustration purposes only. Although they are represented as having a substantially triangular shape and being made of three members, any other configuration allowing each adjustment assembly 100 and 200 to rest on its corresponding side 32 and 34 of the rooftop 30 is considered and included in the present disclosure. For instance, the adjustment assemblies 100 and 200 may have a substantially cylindrical shape (not represented in FIG. 2), and may consist for example of wood logs. The cylindrical shape allows the usage of the same adjustment assemblies 100 and 200 for rooftops 30 having different slopes. Alternatively, the adjustment assemblies 100 and 200 may consist of a single member having a substantially triangular shape (not represented in FIG. 2), for example a rigid triangular cardboard assembly.

The means for securing the two adjustment assemblies 100 and 200 to the pallet 10 are not represented in FIG. 2. However, such means are well known to a person skilled in the art of construction and mechanical engineering, and any appropriate means are considered by the present disclosure. For example, such means may include nails, screws or braces. Such means may also include metallic parts, simultaneously fixed to the pallet 10 and to the adjustment assemblies 100 and 200 with nails, screws or braces.

In a particular aspect, each adjustment assembly 100 and 200 comprises a longitudinal supporting member 110 and 210. The longitudinal supporting member 110 of the adjustment assembly 100 is adapted for resting on the first side 32 of the rooftop 30. The longitudinal supporting member 210 of the adjustment assembly 200 is adapted for resting on the second side 34 of the rooftop 30.

In another aspect, each longitudinal supporting member 110 and 210 defines a specific angle with a vertical axis 150, and the specific angle is substantially equal to an angle defined by one of the two sides 32 and 34 of the rooftop 30 with the vertical axis 150. For instance, the longitudinal supporting member 110 defines an angle θ₁ with the vertical axis 150 and longitudinal supporting member 210 defines an angle θ₂ with the vertical axis 150. The first side 32 of the rooftop 30 defines an angle θ₃ with the vertical axis 150 and the second side 34 of the rooftop 30 defines an angle θ₄ with the vertical axis 150. The angle θ₁ is substantially equal to the angle θ₃ and the angle θ₂ is substantially equal to the angle θ₄. Thus, the longitudinal supporting members 110, 210 and the sides 32, 34 of the rooftop 30 have a complementary shape, providing an optimal support for resting the adjustment assemblies 100, 200 on the rooftop 30.

The rooftop 30 may have a symmetric shape, in which case the angles θ₃ and θ₄ are substantially equal. In this case, the angles θ₁ and θ₂ defined by the longitudinal supporting members 110 and 210 with the vertical axis 150 are substantially equal.

The rooftop 30 may have a dissymmetric shape, in which case the angles θ₃ and θ₄ are different. In this case, the angles θ₁ and θ₂ defined by the longitudinal supporting members 110 and 210 with the vertical axis 150 are also different, and the adjustment assemblies 100 and 200 also have a dissymmetric shape.

The adjustment assemblies 100 and 200 are made of a rigid material, such as for example wood, plastic, rigid cardboard or metal. Alternatively, the adjustment assemblies 100 and 200 may be made of a biodegradable material, such as for example a wood species easily biodegradable, a biodegradable plastic or a biodegradable cardboard.

Adjustment Frame Defined by the Two Adjustment Assemblies

The two adjustment assemblies define an adjustment frame; and the system comprises the adjustment frame and the means for securing the adjustment frame to the pallet.

Referring to FIGS. 3A and 3B concurrently, a side view of the system comprising the adjustment frame 300 is represented. The adjustment frame 300 is defined by the two adjustment assemblies 100 and 200.

The adjustment frame 300 comprises the two longitudinal supporting members 110 and 210. The adjustment frame 300 also comprises a horizontal upper member 320, and two vertical members 330 and 340. An upper edge 112 and 212 of each of the two longitudinal supporting members 110 and 210 is attached to a central section 322 of the horizontal upper member 320. An upper edge 332 and 342 of each of the two vertical members 330 and 340 is attached to an edge 324 and 326 of the horizontal upper member 320. A lower edge 334 and 344 of each of the two vertical members 330 and 340 is attached to a lower edge 114 and 214 of one of the two longitudinal supporting members 110 and 120.

Means 350 for attaching together the two longitudinal supporting members 110 and 210, the horizontal upper member 320, and the two vertical members 330 and 340, are represented in FIG. 3B. Such attaching means 350 may consist for example of metallic parts, secured to the members 110, 210, 320, 330, and 340 with nails, screws or braces. A metallic part 350 is concurrently attached (with nails, screws or braces) to both members it is maintaining attached to one another. However, the present adjustment assembly and system are not limited to such a means for attachment, and any suitable alternative, known in the art, could be used.

The horizontal upper member 320 may comprise the means 360 for securing the adjustment frame 300 to the pallet (not represented in FIG. 3B). Such attaching means 360 may consist for example of metallic parts, secured to the horizontal upper member 320 and the pallet with nails, screws or braces.
